Active Directory and Entra ID sign-ins are now the single biggest attack surface most enterprises operate, and 2026’s breach numbers prove it: identity-driven intrusions dominated the incident reports security teams filed through the first half of the year. That reality has pushed a specific product category, Identity Threat Detection and Response (ITDR), from a Gartner buzzword into a line item CISOs actually budget for. Three platforms keep coming up in shortlists: CrowdStrike Falcon Identity Protection, Microsoft Defender for Identity, and Silverfort. They solve the same problem, credential theft, lateral movement, and privilege abuse, with three genuinely different architectures and three very different price tags. This comparison breaks down the specs, the real 2026 pricing, the deployment tradeoffs, and which platform fits which environment, using only vendor-published data and independently verified third-party benchmarks.
None of these three platforms is a like-for-like swap for the others, which is exactly why so many security teams get stuck comparing feature checklists instead of architecture. CrowdStrike sells identity protection as a module inside a platform most buyers already own for endpoint detection. Microsoft folds it into a license many enterprises are already paying for. Silverfort sells a standalone identity enforcement layer with no adjacent product to subsidize the cost. Those three go-to-market models produce three very different total-cost-of-ownership curves, and this guide walks through all of them with real numbers rather than vendor talking points.

What Is ITDR and Why Every SOC Needs One in 2026
Identity Threat Detection and Response covers the tools that monitor authentication activity, directory changes, and privilege escalation in real time, then either alert a SOC or automatically intervene. It sits next to EDR and SIEM but answers a narrower question: is this login, this Kerberos ticket, or this admin action actually the person it claims to be? Traditional antivirus and even modern EDR agents were built to watch processes and files, not authentication protocols, which is exactly the gap attackers have been exploiting with pass-the-hash, golden ticket, and session-hijacking techniques.
DataForSEO search data puts monthly volume for “itdr” at roughly 1,900 searches and “identity threat detection and response” at 260, both trending upward as the category matures out of the analyst-report phase and into actual procurement conversations. That shift is visible in vendor activity too: Securonix used Black Hat USA 2026 (August 3, 2026) to announce Governed AI Agent Detection and Response capabilities aimed at controlling risk from autonomous AI agents acting as non-human identities, and Sophos pushed its Next-Gen SIEM, priced by users and servers rather than data volume, to general availability on August 15, 2026, explicitly to cut the tool sprawl that separate identity, SIEM, and XDR products create. The category is consolidating fast, which is exactly why picking the right ITDR foundation now matters more than it did even a year ago.
The urgency isn’t hypothetical. Tech Insider’s own reporting on 2026’s breach data shows victim counts already topping 471 million in the first half of the year alone, and a large share of those incidents trace back to a stolen credential, a forged Kerberos ticket, or an over-privileged service account rather than malware. That’s the specific failure mode ITDR platforms are built to catch: not “is this file malicious,” but “is this authentication event legitimate.” Traditional perimeter tools, firewalls, even next-gen antivirus, simply don’t have visibility into that layer, which is why identity has become the fastest-growing line item in enterprise security budgets heading into 2027 planning cycles.
The three platforms compared here approach the problem from different starting points. CrowdStrike bolts identity analytics onto an EDR-first platform. Microsoft builds identity protection natively into the Entra and Defender XDR stack. Silverfort was purpose-built as an identity-only, largely agentless layer that can enforce policy on systems no agent can ever be installed on. That architectural split is the single biggest variable in this comparison, and it drives almost every other difference in this article, from pricing to legacy-protocol coverage.
CrowdStrike Falcon Identity Protection: Architecture and Core Features
Falcon Identity Protection (marketed as Falcon Identity Threat Detection and Falcon Identity Threat Protection, depending on tier) extends CrowdStrike’s existing Falcon sensor deployment rather than introducing a separate product line. Organizations already running Falcon EDR on endpoints get identity telemetry correlated directly against process, network, and cloud activity inside the same console, which is CrowdStrike’s core sales pitch: one graph, one timeline, one analyst workflow instead of pivoting between tools.
Under the hood, Falcon Identity Protection combines lightweight sensors on domain controllers with the broader Falcon agent fleet to watch Kerberos tickets, NTLM authentication, and Active Directory object changes. It is tuned specifically for AD-native attack techniques: golden ticket and silver ticket forgeries, DCSync and DCShadow abuse, and lateral movement chains that pivot through service accounts. CrowdStrike also ships Falcon Privileged Access as a related module for monitoring admin-tier accounts, and both modules feed into the same Falcon XDR correlation engine used for endpoint detections.
CrowdStrike’s published Falcon platform pricing lists three core endpoint tiers, Falcon Go at $59.99 per device per year, Falcon Pro at $99.99, and Falcon Enterprise at $184.99, each also available on monthly billing at $7.99, $14.99, and $19.99 respectively. Identity Protection isn’t included at any of those tiers by default; it’s licensed as a separate per-identity add-on, which means the platform-tier price and the identity price need to be budgeted independently rather than assumed to be bundled. That separation is easy to miss during a first-pass vendor evaluation and is one of the more common sources of budget surprise once a deal reaches procurement.
The tradeoff is ecosystem lock-in. Falcon Identity Protection is sold as an add-on inside the Falcon platform (bundled into Falcon Elite or purchased separately against Falcon Enterprise), so organizations not already standardized on CrowdStrike EDR take on a second agent footprint and a second vendor relationship rather than extending one they already have. CrowdStrike has been vocal about this being intentional, arguing in its own blog that buying identity security from the same vendor as core IAM creates a dangerous single point of failure, a position that implicitly favors pairing Falcon Identity Protection with an existing IAM stack like Entra ID or Okta rather than replacing it.
Microsoft Defender for Identity: Architecture and Core Features
Microsoft Defender for Identity, the successor to Azure Advanced Threat Protection, takes the opposite approach: no endpoint agent at all. Instead, lightweight sensors are installed directly on domain controllers and AD FS servers, where they capture authentication traffic and forward it to the cloud for analysis. That means MDI’s operational burden falls on the AD/infrastructure team rather than the endpoint team, and it avoids adding yet another agent to end-user machines.
MDI’s real strength is how tightly it’s woven into the rest of Microsoft’s security stack. Alerts surface natively inside Microsoft Defender XDR alongside endpoint and email detections, and MDI’s risk signals combine directly with Entra ID Protection’s conditional access engine, so a suspicious authentication pattern detected on-prem can trigger a step-up MFA challenge or session block in the cloud automatically. For organizations already running Microsoft 365 E5 or E5 Security, this integration is essentially free incremental value rather than a new integration project.
Microsoft’s own Defender for Identity technical FAQ lays out the sensor prerequisites in detail: sensors run directly on domain controllers and AD FS servers, require outbound internet access to Microsoft’s cloud (no inbound ports need to open), and support multi-forest AD environments without requiring a redesign of existing trust relationships. That low-friction deployment model is a big part of why MDI shows up so often as the default choice for organizations that are Microsoft-centric but haven’t invested heavily in identity security before. Microsoft also markets a bundled “Microsoft Defender Suite” option at $12 per user per month on an annual plan, which layers MDI together with other Defender workloads for organizations that want broader coverage than the standalone SKU provides but aren’t ready to commit to a full E5 license.
Detection coverage focuses heavily on on-premises AD attack patterns: pass-the-hash, pass-the-ticket, DCSync, DCShadow, and reconnaissance activity like abnormal LDAP queries. Microsoft Sentinel customers get pre-built analytic rules, hunting tables, and workbooks for MDI data out of the box, which shortens the time to a working detection pipeline considerably versus building custom content from scratch. The limitation is scope: MDI is built around AD and Entra ID specifically, and it doesn’t natively extend MFA or access enforcement to non-Microsoft identity providers like Okta or to legacy protocols outside the Windows authentication stack.
Silverfort: Architecture and Core Features
Silverfort is the most architecturally distinct of the three. It was designed from the ground up to be fully agentless, integrating directly with Active Directory, LDAP, RADIUS, and cloud identity providers (Entra ID, Okta, Ping) to broker or mirror authentication requests in real time. Rather than watching traffic after the fact, Silverfort can sit in the authentication path itself, which lets it enforce risk-based access policies, including step-up MFA, on systems that were never built to support modern authentication at all.
That capability, layering MFA onto legacy protocols like RDP, SMB, command-line admin tools, and homegrown or third-party applications that can’t be modified, is Silverfort’s core differentiator and the reason it shows up so often in security reviews for healthcare networks, manufacturing plants, and financial institutions running decades-old infrastructure. Silverfort effectively becomes a policy enforcement extension of whatever IdP an organization already runs, rather than replacing it.
The cost of that flexibility is depth of native EDR/XDR correlation. Silverfort integrates with third-party SIEM and XDR platforms via syslog and APIs rather than owning an endpoint telemetry stream itself, so organizations get strong identity-layer enforcement but still need a separate EDR product for process- and file-level detection. Silverfort also doesn’t publish transparent per-user list pricing; its public pricing page shows tiered plans (with tiers named Core, Plus, Advanced, and Enterprise) without disclosing base per-identity rates, meaning most deals go through a custom quote.
Full Specs Comparison: CrowdStrike vs Defender for Identity vs Silverfort
The table below lines up the core architectural and functional differences across all three platforms based on vendor documentation and product pages current as of August 2026.
| Capability | CrowdStrike Falcon Identity Protection | Microsoft Defender for Identity | Silverfort |
|---|---|---|---|
| Deployment model | SaaS console + Falcon sensor fleet | Cloud service inside Defender XDR | SaaS or on-prem appliance |
| Endpoint agent required | Yes (Falcon sensor) | No (DC sensor only) | No (fully agentless) |
| Domain controller sensor | Yes | Yes | No agent; AD/LDAP connector |
| Primary identity sources | On-prem AD, Entra ID, third-party IdPs via API | On-prem AD, Entra ID (native) | On-prem AD, LDAP, RADIUS, Entra ID, Okta, Ping |
| MFA on legacy protocols (RDP, SMB, CLI tools) | Limited | Limited | Native, real time |
| Native EDR/XDR correlation | Yes, Falcon platform | Yes, Microsoft Defender XDR | No, via third-party API |
| Native SIEM | Falcon Next-Gen SIEM (separate module) | Microsoft Sentinel (native) | None; exports to third-party SIEM |
| Standalone availability | Add-on to Falcon Enterprise/Elite | Standalone SKU or M365 E5 bundle | Standalone, quote-based |
| Automated response | Disable account, revoke session, isolate host | Alert plus Entra ID Protection risk-based CA | Block/step-up auth in real time |
| OT/legacy system coverage | Limited | Limited | Strong |
| Public list pricing | Partial (Falcon tiers published) | Yes, standalone and bundled SKUs | No, custom quote only |
Two patterns jump out immediately. First, only Silverfort natively closes the legacy-protocol MFA gap, which is a decisive factor for any organization still running systems that can’t take an agent. Second, CrowdStrike and Microsoft both benefit from owning the adjacent EDR/XDR and SIEM layers, which shortens time-to-detection for teams already standardized on either platform, while Silverfort trades that native correlation for identity-source breadth.
Pricing Breakdown: What Each ITDR Platform Actually Costs
Pricing transparency varies enormously across these three vendors, and that alone should factor into a shortlist decision. Microsoft publishes clear per-user SKUs. CrowdStrike publishes platform tiers but treats identity as an add-on with pricing that varies by reseller and deal size. Silverfort publishes no base rate at all. The table below consolidates the most consistent figures found across CrowdStrike’s own pricing pages and independent licensing-benchmark research current as of August 2026.
| Platform / Tier | Price | Billing Basis | Source Type |
|---|---|---|---|
| CrowdStrike Falcon Identity Threat Detection | ~$84.99/user/year (list) | Per identity | Third-party licensing benchmark |
| CrowdStrike Falcon Identity Threat Protection | ~$124.99/user/year (list) | Per identity | Third-party licensing benchmark |
| CrowdStrike Identity Threat Protection Bundle | ~$174.99/user/year (list) | Per identity, bundled | Third-party licensing benchmark |
| Microsoft Defender for Identity (standalone) | $5.50/user/month (~$66/year) | Per user, annual commitment | Microsoft CSP / licensing advisory |
| Microsoft 365 E5 Security add-on (incl. MDI) | $12/user/month | Per user, on top of E3 | Microsoft licensing advisory |
| Microsoft 365 E5 (full suite incl. MDI) | $57/user/month | Per user | Microsoft licensing advisory |
| Silverfort | Custom quote (Diamond tier adds 20% to license cost) | Per identity, negotiated | Vendor pricing page |
At the extremes, that’s roughly a $59-per-user annual gap between Microsoft’s cheapest standalone MDI SKU ($66/year) and CrowdStrike’s list price for the Identity Threat Protection module (~$124.99/year), before either vendor’s typical enterprise discounting is applied. Independent licensing-benchmark sites consistently note that CrowdStrike’s actual paid price runs 25 to 30% below list for mid-size deals, which narrows that gap in practice, but the sticker-price difference is real and worth building into a total-cost-of-ownership model before a proof of concept even starts.
The bigger cost variable for most buyers isn’t the per-user rate, it’s whether the organization already pays for the surrounding platform. A shop already on Microsoft 365 E5 gets MDI at effectively zero marginal cost. A shop already running Falcon EDR fleet-wide adds identity protection at the add-on rate rather than paying for a whole new agent deployment. Silverfort, by contrast, is always incremental spend on top of whatever EDR, SIEM, and IdP an organization already runs, which is the tradeoff for its vendor-agnostic architecture.
Total Cost of Ownership: Modeling a 5,000-Seat Deployment
List prices only tell part of the story, so it helps to run a simple model against a mid-size enterprise: 5,000 identities, an existing on-prem AD forest, and an Entra ID tenant already in use for cloud SSO. The table below applies the pricing figures from above at that scale, using the standalone/list rate for each platform rather than assuming maximum enterprise discounting, since discount depth varies too much deal-to-deal to model reliably.
| Platform | Rate Used | Annual Cost (5,000 identities) | Notes |
|---|---|---|---|
| CrowdStrike Falcon Identity Threat Protection | ~$124.99/identity/year (list) | ~$624,950 | Excludes Falcon EDR platform-tier cost if not already deployed |
| Microsoft Defender for Identity (standalone) | $5.50/user/month | ~$330,000 | Lowest entry cost; assumes no existing M365 E5 license |
| Microsoft 365 E5 Security add-on (incl. MDI) | $12/user/month | ~$720,000 | Includes broader Defender workloads beyond identity alone |
| Silverfort | Custom quote | Not publicly modelable | Typically negotiated per deal; request a quote for accurate TCO |
Two things stand out. First, if an organization has zero existing Microsoft security spend, standalone MDI at roughly $330,000 a year for 5,000 identities is meaningfully cheaper than CrowdStrike’s identity module at list price, even before factoring in that CrowdStrike also requires the underlying Falcon EDR platform to be deployed for full value. Second, the moment an organization is already paying for M365 E5 or E5 Security, the marginal MDI cost effectively disappears from this table entirely, since it’s already covered by a license line item that exists regardless of the ITDR decision. Silverfort’s absence from the cost column isn’t a data gap, it’s the honest reality that the company doesn’t publish pricing that scales predictably, so any real budget conversation has to start with a vendor quote rather than a public rate card.
Agent-Based vs Agentless: The Architecture Debate That Decides Your Fit
Every other difference in this comparison traces back to one architectural choice. CrowdStrike leans on its Falcon sensor fleet, which means identity detections benefit from endpoint-level context (what process initiated the authentication, what else that host was doing) but also means every protected endpoint needs an agent installed and maintained. Microsoft avoids an endpoint agent for MDI specifically but still requires sensors on every domain controller, which is a smaller footprint but not zero. Silverfort avoids agents entirely, brokering authentication at the protocol level instead.
Agentless architecture matters most in three scenarios: legacy operating systems that can’t run modern agents, OT and ICS environments where installing anything is a change-control nightmare, and third-party or unmanaged devices (contractor laptops, M&A-acquired infrastructure) where an organization doesn’t control the endpoint at all. In those cases, Silverfort can enforce identity policy where CrowdStrike and, to a lesser extent, Microsoft simply cannot reach.
Agent-based architecture wins when correlation depth matters more than coverage breadth. If a SOC’s top priority is reducing mean time to detect by fusing identity signals with endpoint and network telemetry in one timeline, both CrowdStrike and Microsoft’s native platform integrations outperform a bolt-on identity layer talking to a separate EDR over an API. The honest answer for a lot of mid-size and large enterprises is that this isn’t actually an either/or decision: Silverfort is frequently deployed alongside CrowdStrike or Microsoft Defender XDR specifically to close the legacy-protocol gap those platforms leave open, a combination Silverfort’s own documentation on pairing with Microsoft Defender for Identity addresses directly.
Detection Coverage and Benchmark Data From Independent Sources
Head-to-head, apples-to-apples detection benchmarks specific to ITDR products are still rare, unlike EDR, where MITRE ATT&CK evaluations produce comparable public scorecards every year. What does exist is a mix of vendor-disclosed capability claims, licensing-benchmark research, and analyst-firm coverage that, taken together, gives a reasonably clear picture.
- Licensing-benchmark research (multiple independent pricing-analysis sites tracking CrowdStrike, Microsoft, and Silverfort deals through mid-2026) consistently places CrowdStrike’s identity add-on pricing 2 to 3 times higher per user than Microsoft’s standalone MDI SKU, but also shows CrowdStrike offering the deepest discount flexibility at enterprise scale, with paid prices running well below list on 25,000+ endpoint deals.
- Vendor release cadence is itself a useful proxy for engineering investment: Microsoft ships MDI improvements on the same cadence as the broader Defender XDR platform and Sentinel content updates (Splunk’s own ESCU 6.4.0 detection-content release landed August 12, 2026, illustrating how fast the surrounding SIEM ecosystem is iterating), while CrowdStrike ties identity releases to its broader Falcon platform roadmap.
- Analyst-firm coverage from Gartner, Forrester, and KuppingerCole all track this category, generally framing CrowdStrike and Microsoft as identity-security features of broader XDR platforms, and Silverfort as a specialist identity-fabric and access-control vendor with particular strength in non-web and legacy-protocol coverage. None of the three publishes a single universally agreed “winner” score for ITDR specifically, so treat any vendor claiming an outright analyst win with appropriate skepticism until you’ve read the primary report.
The practical takeaway: don’t shop this category on a single benchmark number, because one doesn’t really exist yet. Shop it on architecture fit, integration depth with what you already run, and a proof of concept against your actual AD forest and authentication traffic.
It’s also worth watching how fast the surrounding ecosystem is moving, because ITDR doesn’t exist in a vacuum. Sumo Logic used Black Hat USA 2026 to announce agentic AI capabilities it claims cut mean time to resolve incidents by nearly 65% and save analysts more than 25 hours a week when applied against large telemetry sets, and PRE Security shipped version 3.8 of its Predictive SecOps platform on August 3, 2026, adding autonomous threat-investigation features aimed at the same identity-and-access problem space these three ITDR platforms address. None of that is a direct benchmark of CrowdStrike, Microsoft, or Silverfort specifically, but it signals where the rest of the market is placing its engineering bets, toward AI-assisted triage layered on top of whichever ITDR foundation an organization has already chosen, not as a replacement for one.
Integration Ecosystem: SIEM, Active Directory, Entra ID, and Okta
SIEM and identity-provider integration depth is often the deciding factor once architecture and price have narrowed the shortlist to two platforms. CrowdStrike’s identity telemetry flows natively into Falcon’s own console and its newer Falcon Next-Gen SIEM module, with API-based export to third-party SIEMs like Splunk, IBM QRadar, and Google Chronicle for shops that haven’t consolidated onto CrowdStrike’s own analytics layer.
Microsoft Defender for Identity’s tightest integration is, unsurprisingly, Microsoft Sentinel, which ships pre-built analytic rules and hunting workbooks for MDI data specifically. Here’s a simplified example of the kind of Kusto Query Language hunt Sentinel customers can run out of the box against MDI-sourced sign-in data to surface suspicious lateral movement patterns:
IdentityLogonEvents
| where Timestamp > ago(7d)
| where ActionType == "LogonFailed"
| summarize FailedAttempts = count() by AccountName, DeviceName, bin(Timestamp, 1h)
| where FailedAttempts > 10
| join kind=inner (
IdentityLogonEvents
| where ActionType == "LogonSuccess"
) on AccountName
| project AccountName, DeviceName, FailedAttempts, Timestamp
| order by FailedAttempts descSilverfort takes the broadest but shallowest integration approach by design: it connects to AD, LDAP, and RADIUS directly for enforcement, and to Entra ID, Okta, and Ping as external IdPs, then exports risk events and enforcement logs to whatever SIEM an organization already runs via syslog or API. It doesn’t try to be the analytics layer itself; it tries to be the enforcement point that every other identity-aware tool can plug into. For organizations running a heterogeneous identity environment, on-prem AD plus Okta plus a legacy RADIUS-based VPN, that breadth is often the single biggest reason Silverfort gets shortlisted over a platform tied to one ecosystem.
Real-World Deployment Scenarios: 5 Environments, 3 Different Winners
Because none of these platforms wins outright, the most useful way to evaluate them is against actual environment profiles. Here are five common deployment scenarios and how each typically shakes out.
- A 15,000-endpoint regional bank already running Falcon EDR fleet-wide. Adding Falcon Identity Protection is the lowest-friction option: no new agent deployment, one console, and identity detections correlate directly with the endpoint telemetry the SOC already triages.
- A mid-market healthcare network on Microsoft 365 E5 with a Microsoft-only security stack. Defender for Identity is close to a sunk cost here since it’s included in the license the organization already pays for, and it plugs directly into the Sentinel and Defender XDR workflows the SOC already uses.
- A manufacturing company running legacy SCADA/OT systems and RDP-heavy remote admin access that can’t take any endpoint agent. Silverfort is close to the only option that can enforce MFA on those systems at all, since neither CrowdStrike nor Microsoft’s identity products extend meaningfully into agentless legacy-protocol enforcement.
- An enterprise using Okta as its primary IdP with a large on-prem AD footprint for legacy line-of-business apps. Silverfort’s native Okta and AD/LDAP integration bridges the two without forcing a migration off Okta, something neither CrowdStrike nor Microsoft’s identity tools are built to do.
- An MSSP managing multiple client AD forests from a single operations center. CrowdStrike’s multi-tenant Falcon console and existing MSSP partner ecosystem generally make it easier to operate at scale across many client environments than standing up per-client Sentinel workspaces or Silverfort deployments.
The pattern across all five: the deciding factor is almost never “which product detects more attacks.” It’s which product fits the identity infrastructure, endpoint footprint, and existing vendor relationships already in place.
Migration Guide: Moving From Basic AD Monitoring to a Full ITDR Platform
Most organizations aren’t starting from zero, they’re starting from native Windows Event Log auditing or a basic SIEM ingesting AD security logs. Moving to any of these three platforms follows a broadly similar sequence, with vendor-specific detours noted.
- Step 1: Inventory identity sources. Map every AD forest, Entra ID tenant, and third-party IdP (Okta, Ping) in use, plus any legacy protocols (RADIUS, LDAP-bind apps) that authenticate outside those systems.
- Step 2: Confirm domain controller sensor prerequisites. Both CrowdStrike and Microsoft require sensors on every domain controller; verify OS versions and network egress rules (typically outbound HTTPS to the vendor’s cloud) before scheduling a rollout.
- Step 3: Run a scoped pilot. Deploy against one AD forest or business unit first rather than the whole environment, since tuning detection sensitivity against real traffic patterns takes days to weeks regardless of vendor.
- Step 4: Tune for false positives. Service accounts and legacy applications with non-standard authentication behavior are the most common source of alert noise in the first 30 days; expect a tuning cycle before the platform is trustworthy enough to drive automated response.
- Step 5: Connect SIEM and SOAR pipelines. Wire detections into existing case-management and SOAR workflows so identity alerts don’t live in a separate console analysts have to check manually.
- Step 6: Enable automated response incrementally. Start with alert-only mode, move to semi-automated response (analyst approval required) after the tuning window, then move to full automation (auto-disable, auto-isolate) only for the highest-confidence detection categories.
- Step 7: Extend to legacy and agentless systems last. If deploying Silverfort alongside CrowdStrike or Microsoft, roll it out specifically against the systems the primary platform can’t reach, rather than trying to run both platforms against the same assets simultaneously.
- Step 8: Decommission legacy monitoring. Once detection coverage and alert fidelity are validated, retire redundant native AD auditing rules or legacy SIEM content that the new ITDR platform has superseded, to cut noise and licensing cost.
Realistic timelines run 4 to 8 weeks for a single-forest pilot and 3 to 6 months for a full enterprise rollout across multiple forests and business units, largely driven by the tuning cycle in steps 3 and 4 rather than the technical deployment itself.
One migration detail worth flagging separately: organizations moving off a legacy on-prem SIEM that was built around raw Windows Security Event Log ingestion (event IDs like 4624, 4625, and 4768) often assume their existing detection rules will port cleanly into a new ITDR platform. They generally don’t. Each of these three platforms builds its own analytics layer on top of richer telemetry than raw event logs provide, so old correlation rules typically need to be rebuilt against the new platform’s native schema rather than migrated as-is. Budgeting analyst time for that rebuild, not just the technical rollout, is one of the most commonly underestimated line items in an ITDR migration project.
Pros and Cons of Each Platform
CrowdStrike Falcon Identity Protection
- Pros: Native correlation with Falcon EDR/XDR telemetry, strong Kerberos/NTLM attack detection, single console for teams already on Falcon, automated response tied directly to endpoint isolation.
- Cons: Highest per-user list pricing of the three, requires the broader Falcon agent ecosystem to get full value, limited native coverage of legacy/non-Windows authentication protocols.
Microsoft Defender for Identity
- Pros: Lowest standalone list price, often already included in existing M365 E5 licensing, deep native Sentinel and Defender XDR integration, no endpoint agent required.
- Cons: Built around AD and Entra ID specifically, weaker out-of-the-box support for non-Microsoft IdPs like Okta, limited legacy-protocol MFA enforcement.
Silverfort
- Pros: Fully agentless, the only one of the three with native MFA enforcement on legacy protocols and OT-adjacent systems, works across heterogeneous IdP environments (AD plus Okta plus Entra ID simultaneously).
- Cons: No published list pricing, always incremental spend on top of an existing EDR/SIEM stack, weaker native XDR-style correlation since it doesn’t own endpoint telemetry.
Use-Case Recommendations: Which ITDR Platform Fits Your Environment
- Already standardized on CrowdStrike Falcon for EDR: add Falcon Identity Protection. The marginal integration cost is close to zero and the correlation benefit is real.
- Already paying for Microsoft 365 E5 or E5 Security: enable Defender for Identity before evaluating anything else. It’s very likely already included in a license the organization is paying for regardless.
- Running OT, ICS, or legacy line-of-business systems that can’t take an agent: Silverfort is close to a requirement, not just a preference, since it’s the only platform of the three built to enforce policy without one.
- Multi-IdP environment (Okta plus on-prem AD, or Ping plus Entra ID): Silverfort’s vendor-agnostic connectors handle this natively where CrowdStrike and Microsoft’s identity products are more tightly scoped to their own ecosystems.
- Budget-constrained mid-market organization with a lean security team: Microsoft Defender for Identity’s lower list price and native Sentinel tooling reduce both licensing cost and the operational overhead of standing up a new analytics pipeline.
- MSSP or large enterprise managing multiple AD forests centrally: CrowdStrike’s multi-tenant console tends to scale operational overhead better across many separate environments than per-forest Sentinel workspaces.
- Regulated industry needing audit-ready MFA on every admin path, including legacy tools: Silverfort’s real-time enforcement layer is purpose-built for exactly this compliance requirement.
The Verdict: Which ITDR Platform Wins in 2026
There isn’t a single winner here, and any comparison claiming otherwise is oversimplifying a genuinely architecture-dependent decision. Based on the pricing, integration depth, and coverage data above, the honest breakdown is: Microsoft Defender for Identity wins on cost and ease of adoption for any organization already invested in Microsoft 365 E5, since the marginal cost is often zero and the Sentinel integration is unmatched. CrowdStrike Falcon Identity Protection wins on correlation depth for organizations that want identity, endpoint, and cloud detections fused into a single analyst workflow and are willing to pay the highest per-user rate of the three for it. Silverfort wins on coverage breadth, specifically for legacy, OT, and multi-IdP environments that the other two platforms simply can’t reach without an agent.
For a growing number of enterprises, the real 2026 answer isn’t picking one, it’s pairing Silverfort with whichever of CrowdStrike or Microsoft already anchors the broader security stack, using the agentless layer specifically to close the legacy-protocol gap the primary platform leaves open. That combination costs more than any single product, but it’s the only configuration among these three that actually covers the full identity attack surface most enterprises are running in 2026.
Frequently Asked Questions
Is CrowdStrike Falcon Identity Protection the same as Falcon Identity Threat Detection?
They’re related but tiered differently. CrowdStrike markets Falcon Identity Threat Detection as the entry-level monitoring module and Falcon Identity Threat Protection as the more advanced tier with automated response capabilities, both sold under the broader Falcon Identity Protection umbrella.
Does Microsoft Defender for Identity require Microsoft 365 E5?
No. Microsoft sells Defender for Identity as a standalone SKU at roughly $5.50 per user per month, though it’s also bundled into Microsoft 365 E5, E5 Security, and E7 Frontier licenses at higher per-user rates that include additional Microsoft security products.
Can Silverfort replace Active Directory or an identity provider like Okta?
No. Silverfort is an enforcement and monitoring layer that sits alongside an existing directory or IdP, not a replacement for one. It integrates with AD, LDAP, RADIUS, Entra ID, Okta, and Ping to extend policy enforcement, particularly MFA, to systems those platforms can’t reach directly.
Which of the three platforms is easiest to deploy without an endpoint agent?
Silverfort is fully agentless. Microsoft Defender for Identity requires no endpoint agent but does require sensors on domain controllers. CrowdStrike Falcon Identity Protection depends on the broader Falcon sensor fleet for full functionality.
Do these platforms work together, or do organizations typically pick just one?
Many enterprises run two of the three together, most commonly Silverfort paired with CrowdStrike or Microsoft Defender for Identity, using the agentless platform specifically to cover legacy and OT systems the primary EDR/XDR-integrated platform can’t reach.
Which platform has the lowest total cost for a mid-market company?
For organizations already on Microsoft 365 E5 or E5 Security, Defender for Identity typically has the lowest marginal cost since it’s included or available as a low-cost add-on. Organizations without an existing Microsoft security investment should compare quotes directly, since CrowdStrike’s list pricing runs higher per user and Silverfort doesn’t publish pricing at all.
Does any of these three platforms stop attacks automatically, or just alert?
All three support some form of automated response. CrowdStrike can disable accounts, revoke sessions, and isolate hosts directly through Falcon. Microsoft Defender for Identity pairs with Entra ID Protection’s risk-based conditional access to trigger step-up authentication or session blocks. Silverfort can block or require step-up authentication in real time as part of its enforcement path.
Is ITDR the same thing as a SIEM or XDR?
No. ITDR is scoped specifically to identity and authentication activity, while SIEM aggregates log data broadly across an environment and XDR correlates detections across endpoint, network, and cloud telemetry. In practice, ITDR platforms like the three compared here feed data into a SIEM or XDR rather than replacing it.
